FREEZER.

Specification of Letters Patent.

Patented July 16, 1912.

Application filed October 19, 1911. Serial No. 655,494.

To all whom it may concern:

Be it known that I, VILHELM AUcUsr MODEL, a subject of the King oflVurttemberg, and residing at Feuerbach, near Stuttgart, in the GermanEmpire, have invented certain new and useful Improvements in Freezers,of which the following is a specification.

My present invention relates to agitating devices such as freezers orthe like which comprise a bucket or stationary receptacle and a smallerreceptacle revoluble within the stationary receptacle, and such otherdevices, as for example, dashers which appertain thereto.

The principal objects of my invention are to provide a bridge memberwhich spans the mouth of the bucket and supports the inner revolublereceptacle, with respect to its axis for actuation, the said bridgemember and appertaining parts being such as to facilitate assembling ofthe various members in operative relation to each other or dismemberingof the device; to simplify the device as a whole; and, to enable theparts to be brought into operative relation to each other regardless ofdistortion of some of the elements, such as shrinkage or expansion ofthe material of which the bucket is formed due to dryness or dampness towhich they are usually subjected. v

In the drawings, forming a part of this specification :Figure 1 is a topplan View of a freezer embodying my invention. Fig. 2 is a fragmentaryvertical central sectional view through the freezer embodying myinvention.

In the drawings, where similar characters refer to similar parts, theinvention is disclosed as applied to an ice cream freezer, whichcomprises generally, a bucket or outer receptacle 1, an inner receptacle2, and a bridge member 3, spanning the mouth of the former andstabilizing the latter.

The outer receptacle is provided with two upstanding pins or lugs 1 and5, spaced apart from each other adjacent the upper margin thereof. Atthe opposite side of the receptacle 1, from the pins 1 and 5, is anotherupstanding pin or lug 6, having a notch 14, for a purpose to besubsequently disclosed.

The inner receptacle 3 is mounted to revolve within the receptacle 1, inany suitable manner, not shown in the drawings,

and stabilized with respect to its axis of rotation by the bridge member3.

In orderto operatively support the receptacle 2 as described, the bridgemember 3 is provided with a socket member 10 which receives anupstanding annular flange 11 on the cover of the receptacle 2, while thedasher spindle 9, is formed polygonal at its end and is received by acomplementary formed aperture 8 in the bridge member 3. The bridgemember 8 has an aperture 7, adjacent its end, permitting such member toembrace the pin (3 in such a manner that the notch 14 is disposed, inpart, above the top of the member 8. Adjacent this aperture 7, themember 3 carries a bolt 13, pivoted on pin 12, which may be turned toproject into the notch 14 and bind the bridge member against the top ofthe receptacle 1.

In assembling the device, the receptacle 2 and dasher spindle 9 arepositioned within the receptacle 1. The bridge member 3 is then placedwith its one end between pins 4 and 5, and its other end embracing thepin 6. It is to be noted that, because of the relative coaction of thepins 4:-5 and pin 6, with the bridge member 3, the latter may be letdown in place between pins 4 and 5 and embrace pin 6, to receive andstabilize the receptacle 2 and dasher spindle 9, by

movement in a vertical plane. This means of assemblage, is incontradistinction to known devices where a loop is provided for one endof the bridge member and in assemblage the bridge member is first placeddiagonal with its end inserted into such loop, which then forms a pivotto swing the bridge member in place. This last described procedure ofassemblage is objectionable inasmuch as the bearing for the innerreceptacle and dasher spindle must be made relatively larger than themembers they receive in or der to allow the bridge member to be swung inplace. It is further to be noted that the receptacle 1, in practice, isusually made of wood which contracts and expands so that the diameter isaltered according to whether the bucket is exposed to dryness ordampness and consequently the distance between the pins 4:-5 and pin 6is seldom uniform. By the disposition of parts, according to myinvention, considerable alteration of the bucket will not render thedevice inoperative, since the bridge member is retained in a rigidposition against upward movement by the bolt 13, at one end only of themember and as a result there is no positive position where the other endof such member must engage the pins 4: and 5, so long as such endsremain intermediate the said pins.

In other words, the bucket 1 may shrink or be bent to assume an ovalcross section and such alteration will only effect the positioning ofthe pins at and 5 longitudinally of the member 3, they, the pins, stillpreventing lateral displacement of the member 3.

I claim 1. In a device of the character described,

the combination of an outer receptacle, an

inner receptacle, two upstanding lugs adjacent the margin of said outerreceptacle,

2. In a device of the character described, the combination of an outerreceptacle, an inner receptacle carrying an upstanding annular flange, adasher spindle projecting from and above said inner receptacleconcentric to said flange and having a polygonal end, two upstandinglugs adjacent the margin of said outer receptacle, another upstandinglug, opposite said first mentioned lugs, adjacent the margin of saidouter receptacle, a bridge member, spanning the mouth of said outerreceptacle and provided with a socket adapted to receive said flange ofsaid receptacle and an aperture formed complementary to said spindle endto receive the same for stabilizing the receptacle and spindle, saidbridge member being adapted to lie between said first mentioned lugs andembrace said second mentioned lug, and a device adapted to coact withsaid second mentioned lug to normally prevent upward movement of saidbridge member.

In testimony whereof I aflix my signature in presence of two witnesses.
